Definitions

  • the invention relates to a connector for an optical fiber, which is connected to a plug with a centering pin, which can be inserted into a centering socket, which is received in a holding body, which is fixed to a backplane of an electrical assembly frame.
  • Such a connector is e.g. made known by DE 9010 866 U1. Then the backplane is provided with free holes for the plug connections.
  • the plug has a union nut which can be screwed to a threaded piece connected to the centering bush.
  • the union nut extends from a central section of the connector to beyond the centering pin. It is knurled throughout for the purpose of manual operation.
  • the invention has for its object to increase the screen security.
  • the contact part on the union nut is axially displaceable, whereby differences in the thickness of the backplane can be compensated.
  • the key surfaces can be formed as simple flats, which are accessible by a simple open-ended wrench, which encompasses the webs and the key surfaces.
  • a backplane circuit board 1 is provided with a large-area metallic shield layer 2 and has an open hole 4 in the area of a plug connection for a light guide 3.
  • a holding body 6 for a centering bushing 7 is attached to this, on the inside of the backplane 1 facing the assemblies 5, into which a centering pin 8 of a plug 9 projects, to which the coated light guide 3 is connected.
  • a mating connector of the assembly 5 also has a centering pin 8 which abuts the centering pin 8 for the light guide 3 in the middle of the centering bushing 7 and is thus connected to the latter.
  • the plug 9 is provided with a union nut 11 which abuts a screwed-on stop ring 12. It has an internal thread at its end facing module 5, with which it can be screwed onto an external thread formed on centering bushing 7. As a result, the stop ring 12 of the plug 9 is axially clamped between the centering bushing 7 and a stop shoulder 13 of the union nut 11, as a result of which the plug 9 is fixed to the centering bushing 7 with the centering pin 8.
  • the union nut 11 is connected to the area of the stop ring 12 to the light guide 3 to a hollow cylindrical sleeve part whose inner diameter is larger than the largest outer diameter of the connector 9.
  • the union nut 11 projects beyond the connector 9 and carries one at its free end knurled actuating section 14, which is also in close proximity to one on the backplane 1 attached electrical cable connector 15 is easily accessible by hand.
  • a metal body 16 preferably made of aluminum, is fastened by screws 10 and contacted with the shield layer 2.
  • a sleeve-shaped contact part 17 is pushed over the union nut 11 and screwed into an internal thread of the metal body 16.
  • the free end of the contact part 17 is provided with narrow longitudinal slots 18, between which spring tongues 19 remain, which are bent towards the union nut 11 and rest thereon in a contact cut 20, which is smooth-cylindrical and located between the actuating section 14 and the stop ring 12 located.
  • the plug 9 is provided with flattened key surfaces 21 which are accessible from the outside through window-like openings 22 in the union nut 11.
  • a cross section through these parts is shown in more detail in Figure 2. It can be seen from this that the openings 22 are cut so deep into the union nut 11 that the width of the webs 23 which remain stationary is at most equal to the width across flats of the key surfaces 21.
  • the plug 9 can thus be secured against twisting by a transversely attached open-ended wrench 24 when the stop ring 12 is screwed on.
